"(Figsr 1 and by nuts operated by chain and sprocket gearing 1a. The base 1 supports. a fixed central vertical spindle 2. The spindle 2 extends almost the full height of the machine '5 and upon it revolves a hollow triangular prism-or flat-sided column 3 to-which thefinishing molds 4 are hinged upon horizon-l tal fulcrumsf. The lower. end of the column 3 has a'fi'ange 6 which is supported by means of a ball bearing 7 just above'a' table 8 adapted; torevolve upon a ball-bearing 9. The table 8 revolves with a toothed quadrant 110 which meshes with a rack 11 (see also Fig. 3) .havingaifulcrum atone, end upon a crank pin'12 carried by a wheel 13. The free end of the rack 11-is held in mesh; with the quadrant 'lQbyvertical pins or rollers 14 on lugs1-51projecting from a loose ring 15a. The rack is guidedbetween the pins;- "'14. The wheel 13- is'mounted-to turn with worm gearing 16 driv'enfrom' any suitable source of power and it will-be understoodthat rotation of the wheel 13 will reciprocate the rack 11 which in turn will" oscillate the quadrant 10 and table'- 8 through an angleof 120degrees or' onethird'of a complete revolution. Any other suitable gearing may be 'rovided for oscillating'the table. A n the table 8 are mounted the cam plate 361? (Fig. 11) for opening and closing the paris'on molds 1'8 andineck-ring 51, the track 19 for raising and lowering the finishing molds 4, the cams 20 and 20a for raising and I lowering the parison'molds 18 for "gather; #ing and blowing, and also the'cam 64 (Fig.

4)"for operating the shears; i

A driving pin 21 (Figs.1,8 and 19") slides vertically-in ahousing 22 'on the underside of the table 8 and carrie's'at its lower end'a effroller 23 which is adapted to ride over and under a fiXed-arcuate track 24 when the table oscillates. During "the forward movement of the table 8, the roller 23 rides on the track I 24 and theupperend ofthedriving'j'p'in.

4521 is projected bysprings 34 into a hole 25- in the columnflangeti, thereby locking the mold-supporting colurnfn' to the table during the forward j moi'ement of the latter.

, Atthe end of itsifor'iv'ardstroke, the driv 5 ing pin 21 is withdrawn froni the hole" 25 7 inthe flange 6 by 'a lever 26 which depresses" a crosshead 27 on the driving pin 21'. The lever 26 is connected by links'28 to verti- ,cally-movable locking pin 29' which; moves 55 in a fixed' bracketor:l1'ousing 35in such manner that, when theflock-"p'in 29 is raised, the T drive-pin '21 is lowered? The lock-pin 29 is raised and lowered by"the-provislonion' the lock-pin-29 of aroller 30 operating in a 60 cam groove 31- inthe wheel 13 .;"The" leeking-pin 29 when raised passes through an arcuate slot 32 in the table 8' into one o'f' three locking holes 33 provided in the flange 6 of the mold-supporting column at'12 0 'de- 6 grees apart. The: end of'the fixed track-24 is inclined so as to assist in drawing down the drive-pin 21 at the end of its forward stroke. The roller 23 rides under the track 24 on the return stroke of the table 8 and thereby holds th'e'drive pin 21 out of opera tion. Thusthe drive pin 21 rotates the mold-supporting column during each forward stroke andthe locking pin 29 holds .the mold-supporting column stationary dur' ing eachreturn stroke ofthe table.

The parison. molds 18 (Figs. 1, 5 and 6) Iareeach split as usual, thetwo halves being each carried by an arm 36 pivoted upon a bracket 37 which isfixed upon a spindle 38 and is fixed to a crosshead 38a fixed to vertical guide rods 39-which slide in brackets 40 fixed to the mold-supporting column 3. The lower-ends of theguide r0ds 39 carry a crosshead 41' on which is mounted a roller 42- which cooperates with the cams-20 and 20a on theoscillatin'g table 8to raise and lower the pa'i'ison molds. rThe parison mold [is opened and closed byconnecting the parison arms 36 by pin and slot connections to bell-cranks 43 turning on the rods 39 and connected by rods 44to a crossh'ead 45 (simi lar to the crosshead 53a of Figs. 16 and 17) havin a roller 45a (Fig-16) movable in a slotte link 46 carried 'by'a slide 46a moved towards and away from the parison by an arm 47 proje'cting from a vertical shaft 48 *whic'h-carries atits lower end a roller 49 running in acam groove 5O (Fig. 4) in the cam plate 17;.11 The cam'groove 50 is shaped to "close and-open the parison molds at the required times and the cams, 20 and 20a raise and lower theparison asrequired. The slotted link 46'allows the parison mold to be opened andclosed either in its raised or lowered'p'ositiom l .1

heholder f the neck'ring 51' (Figs. 16 and 1-7) of the parison mold similarly consistsof a pair-of pivoted arms 52 opened and, closed by actuating links 53 :connected ,by a crosshea'dfl53a' having a-central roller which works in a slotted link 54 having a slide'54a moved towards and away from the I mold by a lever 55 projecting from a vertical shaft 56-which'carries on an arm at its lower end a roller '57 which runs in a cam groove-'58 (Figs- 2 and 4)f'in'the cam plate mold ispivoted on a 'vertical shaft 60 carend of the shaft 60, alever on the lower end of shaft61a having a pin or roller 63 which cooperates with-acam 64 on the cam plate 17 ;An annular guide 65 fixed on the'oscillating table 8 guides the movement of the rollers 63 as-the'table' oscillates to and fro in relation to the column.'= .1 T

The track 19 forraising andlowerin'githe finishing molds 4'extends'substantially twothirds of the way around the table and consists (as shown in Figs. land 3.) of a rail 7 tance from-the central column and at such a height as to support the finishing mold -1- m ,in an upright position as shown. The finish ing molds 4 are each mounted upon a base;-

vacuum pipe for gathering the charge.

VVhenthdport 88a traverses slot 104, the: parison is blown, and when the port 88a I v plate or member 66' which is pivoted on the fulcrum 5 and hasend-rollers'67' whichrun upon the track 19..

The base plate normally hangs down- Wards. at an angle, with the finishing mold projecting-outwards and-upwards therefrom,

may be more readily. understood, the seiently grasped when the finishing mold is in so that the neck ofthe bottle can be convenggthe delivery position. t

The opening and closing of the finishing mold 4 is effected by pivoting the'two halves of the finishing mold on a pin 68 (Figs. 13 and 14) on the base: member 66-and pro- Ividing two pins, rollers or projections 69 on a slide 71 for engagingan'arcuate slot '70: in each half ofthe mold to close and open the mold when the slide 71isreciprocated; The slide 71 is operated by providing'it;

aowith a roller 72 which rides along a cam bar 73' (Fig. 15)'fixed at the highest. point of the track 19'for closingthe mold. The cam bar 73 is pivoted atTt'and heldin the path of the roller 72 bya spring '75; A fixed cam 99 (Figs. land 3)-opens the finishing mold at thevdelivery position.

The charge of glass is drawninto the pariQ son mold by creating a vacuum in the blow head 76 of the'parison mold.. This is carried in a bracket 77 (Figs. 7 and '8) and has a plunger 78-connected to links 79-and 80y the latter having a roller8lmovablejina, slotted link 82carriedby slide rods 83, which slidein cross heads 84 and 85. Through the! cross-head 84 slides thespindles 38. v The crosshead 85 is fixed to the column 3.v A

of the machine. A pipe 88'leadsto theblow 5 head which has ports controlled by the plimger 78. The pipe 88 has COIll18C10nSi 89 and 90 to a valve chest .91 containing a p1s ton valve .92. which controls an-air inlet pipe 93 and a vacuum pipe 94.

the blow head and for controllingthe vacuinn connection This timing valve [is mounted on the top of the triangular column 3 (Fig. 12) within a cylindrical valve casing,

65 101. The'v lve 100 thus remains stationary- I The valve 92' 55 .is lifted by aroller 95 (Fig. 12) on its lower end cooperatingwith a cam track 96 fixed; on the column 3 vand is depressed by a linger,

whilst ;the valve "case" 101 rotates with the triangular column. Thefvalve 10O is inter- 1 posed" between :the blow-heads 76" and the,

valve-'92 (Fig.r\l2) and. thei pipes 88,fron1 the three .blow-heads openv into the valve caseJlOl. The fvalve lOOhason itslunderside threeslots or recesses 102, 103 and 104:

which-connect respectivelyto a vacuum pipe 89.:a'ndtocompressed-aiii pipes 90=and 900:. When the port 8'Sa (Fig. 12), traverses the? slot 102, tliesblow -head is connectedfto the traverses slot 103, the blow ehead is supplied withair 'forblowing the bottle.

In order-that the operation of-the machine quence of operations carried out by one of the parison molds willnow be described;

As shown in Figs; 1 and 3, the position at which 'the'parison mold dips for gathering: the charge of-glass is designated position N o. 1, .the'position at which the parison is transferred to the finishing mold is designatedNo. 2* position and the position No. 3 is'theposition in which the parts have completedxtheir sequence of operations.-

The'parison mold 18'as it approaches the gathering "position. is: closed and the plunger 78is depressed (as sho-wn' iniFig. 7 e) by the cooperation of cam 87 with roller 86 in readiness to formthe usual depression in the neckof the parison. Theparison mold isbrought into the gathering position by the forward rotation of-t'he table 8. i As soon as thelatter completes. "its 3 forward movement, the column S is locked in a stationary position and the parison mold is then-in position No. lw'ith: the roller 42 resting on the top of the cam 20%; -As soon as the table 8 reverses, the cam 20a is moved from under the roller 42,*causing the. parison niol'dto. dip into the I I ypositionshown in Fig.'7 i. e. the blow-head roller 86 carried-by the slide rods 83 engages-- a cam groove in a fixedcam ,87 at the headis connected-to thervacuum or suction pipe 94: and a chargeof glassis thus drawn into the parison-mold.

'J list before the table 8 =reaches the end of its reverse'movement, cam '20 raises the parisoii molds At. the 'sametime, the shear blade -59(iis operated by its cam to trim the parison. r: :9; c l v i The table-"8 then commences its forward movement -and carries with it the column 3 and parison molds; During this movement the finishing moldl hangs down in the position shown-in Figs; 1 2. During this movement also, cam 96 li fts valve 92, closing vacuum connection 89, 94: and opens air connection 90, 93. The timing valve-100, how.- ever, cuts ,ofi' communication between air pipe 90f'and blow head until groove 104-connectsv with portBSa. o In. the meantime,

plunger-78 has beeii 'withdrawnbyc'am:8 7 operating roller 86. The charge 1 of glass is thusblown. The shears are lowered until just clear ofthe parison by mechanism not shown. .As soon as the parison mold reaches No. 2 position, the table 8 is at the end ofits forward stroke. On the reverse movement of the table, the returning track 19 lifts the finishing mold 4 to its highest position. At

the same time the parison is released from the parison mold'by the cooperation 'of the cam groove .with' the rolleri49, and the parison is dropped into the finishing mold by the cam 20 riding from under the roller 42. The finishing mold is then closed upon the parison by the cam bar 73ron the high part of the track 19. The table 8 then commences its forward travel again and the' bottle is blown asthe parison travels from the position No. 2 to position No.. 3. On the next reverse movement ofcthe table 8, the neck ring 51 is opened by the cooperation of the cam groove '58 with the roller 57. -This allows'the cam 20a to raise the blow head, neck ring and open parison mold to their. highest positions. At the same time the finishing mold rides down the returning track 19 until it again hangs downwards.-

The neck ring and parison mold close during the returning movement of the'track so that, on the next forward movement of the table, the parison mold "is inreadiness for gathering and the plunger is depressed, the parison mold moving intothe gathering position. The finishing mold with the blown bottle is carried round-by the intermittent rotation ofthe table, 8 until, when it again reachesthe position No. 2, and still hangs downwards, it is struck by a fixed cam-99 on the rear end ofthe track 19 to open the finishing mold in readiness forienabling the V finished article to be removed as the opened said member.

, finishing mold is being lifted by movement of the track.
